I have an overnight in Philadelphia, and was thinking to book the Sofitel Philadelphia, any idea if it is worth spending money for a taxi and everything from the airport? On google maps it says its only 20 minutes, I can't decide whether I should take that or just book the airport Marriott. Would love to hear some of your suggestions, I have never been to Philly before, and my flight lands at 3 pm so I do have the whole day, with my flight the next day being at 9 am. Thanks!
